我是Android新手,并为gcm推送通知做一个演示应用程序.

我已经开发了所有这些代码,并且GCM推送通知正在我的环境中的设备上出现,但是当我在其他网络设备中测试此代码获得注册ID时,但是当向云发送消息时服务器端获得不匹配的发送者ID响应.我的代码如下:

        checkNotNull(CommonUtilities.SENDER_ID, "SENDER_ID");

    GCMRegistrar.checkDevice(this);
    GCMRegistrar.checkManifest(this);

    setContentView(R.layout.activity_push_android);
    mDisplay = (TextView) findViewById(R.id.display);

    final String regId = GCMRegistrar.getRegistrationId(this);
    Log.i(TAG, "registration id =====  " + regId);

    if (regId.equals("")) {
        GCMRegistrar.register(this, CommonUtilities.SENDER_ID);
    } else {
        // Device is already registered on GCM
        if (GCMRegistrar.isRegisteredOnServer(this)) {
            // Skips registration.
            Toast.makeText(getApplicationContext(),
                    "Already registered with GCM", Toast.LENGTH_LONG)
                    .show();
        } else {
            // Try to register again, but not in the UI thread.
            // It's also necessary to cancel the thread onDestroy(),
            // hence the use of AsyncTask …
